I don't get the need for a DVD. such a waste. burning, printing, distribution...
Software update it. or at least an installer download.![]()
The installer needs exclusive access to the system so it can write certain portions of it. That requires burning a disc or another medium. Having Apple do it ensures reliability and quality control from Apple's perspective. Not to mention that the vast majority of their customers do not have the infrastructure needed to maintaina 6 gig download (nor would ISP's be a big fan of that) to justify maintaining servers for such a large download - the costs would not just be there.
